仿淘宝星级评分效果

最近一个小项目需要一个星级评分的效果，所以去淘宝偷了一个，但是还得加载YUI很不爽，还是自己动手写一个吧～


HTML:

<!--
	# 星级评分
	# star:value = 分数
-->
<div class="shop-rating">
	<span class="title">物流公司的服务：</span>
	<ul class="rating-level" id="stars2">
		<li><a class="one-star" star:value="20" href="#">20</a></li>
		<li><a class="two-stars" star:value="40" href="#">40</a></li>
		<li><a class="three-stars" star:value="60" href="#">60</a></li>
		<li><a class="four-stars" star:value="80" href="#">80</a></li>
		<li><a class="five-stars" star:value="100" href="#">100</a></li>
	</ul>
	<span class="result" id="stars2-tips"></span>
	<input type="hidden" id="stars2-input" name="b" value="" size="2" />
</div>
<!-- END 星级评分 -->

CSS:

/* 星级评分 */
.shop-rating {height: 25px;overflow: hidden;zoom: 1;padding: 2px 0px;position: relative;z-index: 999;}
.shop-rating span {height: 23px;display: block;line-height: 23px;float: left;padding-top:2px;}
.shop-rating span.title {width: 125px;text-align: right;margin-right: 5px;}
.shop-rating ul {float: left;margin:0;padding:0}
.shop-rating .result {margin-left: 20px;padding-top: 2px;}
.shop-rating .result span {color: #ff6d02;}
.shop-rating .result em {color: #f60;font-family: arial;font-weight: bold;}

.rating-level {background-position: 0px 0px; width: 120px;height: 23px;position: relative;z-index: 1000;}
.rating-level li {display: inline;}
.rating-level a {line-height: 23px;height: 23px;position: absolute;top: 0px;left: 0px;text-indent: -999em;*zoom: 1;outline: none;}
.rating-level a.one-star {width: 20%;z-index: 6;}
.rating-level a.two-stars {width: 40%;z-index: 5;}
.rating-level a.three-stars {width: 60%;z-index: 4;}
.rating-level a.four-stars {width: 80%;z-index: 3;}
.rating-level a.five-stars {width: 100%;z-index: 2;}
.rating-level .current-rating,.rating-level a:hover{background-position:0 -28px;}
.rating-level a.one-star:hover,.rating-level a.two-stars:hover,.rating-level a.one-star.current-rating,.rating-level a.two-stars.current-rating{background-position:0 -116px;}
.rating-level .three-stars .current-rating,.rating-level .four-stars .current-rating,.rating-level .five-stars .current-rating{background-position:0 -28px;}

结构和样式是偷淘宝的！！


JS：

var Class = {
	create: function() {
		return function() { this.initialize.apply(this, arguments); }
	}
}
var Extend = function(destination, source) {
	for (var property in source) {
		destination[property] = source[property];
	}
}
function stopDefault( e ) {
	 if ( e && e.preventDefault ){
		e.preventDefault();
	}else{
		window.event.returnValue = false;
	}
	return false;
} 
/**
 * 星星打分组件
 *
 * @author	Yunsd
 * @date		2010-7-5
 */
var Stars = Class.create();
Stars.prototype = {
	initialize: function(star,options) {
		this.SetOptions(options); //默认属性
		var flag = 999; //定义全局指针
		var isIE = (document.all) ? true : false; //IE?
		var starlist = document.getElementById(star).getElementsByTagName('a'); //星星列表
		var input = document.getElementById(this.options.Input) || document.getElementById(star+"-input"); // 输出结果
		var tips = document.getElementById(this.options.Tips) || document.getElementById(star+"-tips"); // 打印提示
		var nowClass = " " + this.options.nowClass; // 定义选中星星样式名
		var tipsTxt = this.options.tipsTxt; // 定义提示文案
		var len = starlist.length; //星星数量
		

		for(i=0;i<len;i++){ // 绑定事件 点击 鼠标滑过
			starlist[i].value = i;
			starlist[i].onclick = function(e){
				stopDefault(e);
				this.className = this.className + nowClass;
				flag = this.value;
				input.value = this.getAttribute("star:value");
				tips.innerHTML = tipsTxt[this.value]
			}
			starlist[i].onmouseover = function(){
				if (flag< 999){
					var reg = RegExp(nowClass,"g");
					starlist[flag].className = starlist[flag].className.replace(reg,"")
				}
			}
			starlist[i].onmouseout = function(){
				if (flag< 999){
					starlist[flag].className = starlist[flag].className + nowClass;
				}
			}
		};
		if (isIE){ //FIX IE下样式错误
			var li = document.getElementById(star).getElementsByTagName('li');
			for (var i = 0, len = li.length; i < len; i++) {
				var c = li[i];
				if (c) {
					c.className = c.getElementsByTagName('a')[0].className;
				}
			}
		}
	},
	//设置默认属性
	SetOptions: function(options) {
		this.options = {//默认值
			Input:			"",//设置触保存分数的INPUT
			Tips:			"",//设置提示文案容器
			nowClass:	"current-rating",//选中的样式名
			tipsTxt:		["1分-严重不合格","2分-不合格","3分-合格","4分-优秀","5分-完美"]//提示文案
		};
		Extend(this.options, options || {});
	}
}

基本上注释里已经写的很清楚了！我没什么可说的了！欢迎大家继续改进！！
